Roadmap and Validation

The synchrony framework is intentionally phased. The current implementation covers the first reviewable pass across state cubes, events, four primitive operators, spatial modes, biological cubes, and same-pixel coupling.

Current Implementation

Implemented

State constructors, event detection, occurrence, severity, timing, duration, biological rasterization, alignment, and same-pixel coupling.

Partly Implemented

Neighbor summaries, all-pairs outputs, block hooks, and event matching are usable but still early.

Deferred

Null models, bootstrap intervals, event graphs, recurrence, followed-by logic, climate networks, and streaming-scale event catalogs.

Synthetic Truth Cases

The roadmap calls for deterministic examples where each primitive recovers only the feature it is supposed to measure:

• Independent fields.
• Shared events.
• Lagged events.
• Shared occurrence with independent severity.
• Shared timing with different duration.
• Distance-decay synchrony.
• Spatial modules.
• Frost followed by biological boom.
• Repeated fire with recurrence effects.
• Compound drought-plus-heat events.

The current website assets exercise shared events, lagged responses, timing lags, and duration differences. More synthetic validation notebooks should be added as the grammar matures.

Diagnostics Still Needed

• Event prevalence maps.
• Synchrony-distance curves.
• Threshold sensitivity surfaces.
• Bootstrap confidence intervals with block methods.
• Null models preserving autocorrelation and seasonality.
• Metric comparison panels.
• Matched-event timelines.
• Cross-process lag curves for multiple mechanisms.
